There are storms and sandstorms in many places in the north. What harm will sandstorm bring?

After the May Day holiday, Beijing ushered in sandstorm weather. There have been many sandstorms since May 6th? Attack? After Beijing, the air quality once fell into a serious pollution level. With the gradual strengthening of the wind, windy and dusty weather began to affect the urban area of Beijing. The concentration of PM 10 in Beijing rose instantly, exceeding 500 μ g/m3 in most areas, and the city's air quality fell into a serious pollution level.

Dust comes from two places. One is western Inner Mongolia, and the other is western Gansu. The second is the vast area between South Mongolia and Inner Mongolia in China. ? Western Inner Mongolia and western Gansu are the loess plateau areas in China, with bare soil and heavy wind and sand. The wind in the west swept bare sandstorms across Beijing, causing sandstorms in Beijing. Due to climatic reasons, there is less precipitation and dry climate in the vast area at the junction of South Mongolia and Inner Mongolia, which leads to a large number of sand and dust breeding. It provides a sand source for the formation of sandstorms in Beijing.

Sandstorm is extremely harmful, which will have an impact on the environment and biology. The terrible thing about sandstorm is that it can transport fine particles thousands of miles away, and there will be a lot of toxic minerals and chemical and biological pollution in this dust, which will cause damage to respiratory tract and lungs. If you live in an environment polluted by sandstorms for a long time, your lung function will be seriously damaged and your immunity will decline. When a sandstorm comes, there is a lot of dust in the air, which will reduce visibility and easily lead to traffic accidents. In severe cases, it will be forced to block roads, which will bring a lot of inconvenience to people.

The sandstorm is coming, so everyone should try to reduce travel. If it is unavoidable, please wear a mask and take protective measures. Relevant departments should formulate a series of measures to reduce the occurrence of sandstorms. For example, increasing vegetation coverage, planting trees and strengthening environmental protection. Only in this way can sandstorms be effectively reduced.
